Hybrid Materials & Methods

Abstract

A hybrid material may be configured as a hybrid fabric. An illustrative embodiment of a hybrid fabric may be constructed of two yarns engaged with one another and exhibit a moisture absorbency of ten seconds or less and a differential in moisture spreading speed one a first face of the hybrid fabric compared to that of a second face. Another illustrative embodiment of a hybrid fabric may be constructed of two yarns engaged with one another and exhibit a moisture absorbency of ten seconds or less and a planar wicking rate of at least 2.5 mm/min. Another illustrative embodiment of a hybrid fabric may be constructed of two welded yarns produced via welding processes differently configured such that the resulting welded yarns have one or more differing properties. Illustrative embodiments of such hybrid fabrics include but are not limited to pique and jersey and pique fabrics constructed of cotton.
